Mine as well. Always CSPAN which is not on my recording list. Mistery. Maybe the leftist gremlins are at it again.The last few days all three of my TiVo's (2 Bolts and 1 Roamio) been using all tuners to record 1 minute manual recordings on channel 109 and 110 (C Span & C Span 2). I have Fios. These are occurring at random times of day and using all tuners (suggestions are turned off). I discovered this because the Mini said all tuners were in use. I thought that might be possible so I changed the dvr that it was linked to and got the same message. I've been with TiVo for a long time and this is the first time this has happened. Does anyone have any idea what might be going on? Thank you.
